Answer: 340 inches

Step-by-step explanation:

1/2 (Perimeter)(Slant Height) + Base Area

Base Area is 100

Slant Height is 12

Perimeter is 40

1/2(40)(12) + 100

=340 inches

Answer:

Ummm bubble gum....lol

JK, the answer should be 340in. :]]

10 x 10 is 100

10 x 12 = 120

120 divided by 2 is 60.

60 x 4 is 240.

Now 240 + 100= 340.

Answer: 10, 15

Step-by-step explanation:

Given

Stephanie wants to raise at least $800

she plans on selling VIP tickets for $20 each and general admission for $40 each

suppose there are x and y tickets for VIP and general admission

[tex]\therefore x+y\leq 25\\\\\Rightarrow 20x+40y\geq 800[/tex]

solving above two inequality

Stephanie must sell 10 tickets for VIP and 15 tickets for general admission

Answer:

The answer is 24

Step-by-step explanation:

The top one is basicly 36÷3 and that = 12

The second one is 12+? So you have to find out what (?) is. You do this by doing 28-12=16 16÷2=8

The next one is 8-?=4 so what we do it 8-4=4

The final one is all the answers added together so 12+8+4= 24 -(sorry for any spelling mistakes)

what the other guy said

Answer:

length x width

Step-by-step explanation:

Answer:

Length times width

Usually, it is used as (length times width times height).

Answer:

Solution given:

now

base[b]=11

hypotenuse [h]=5+11=16

perpendicular [p]=14

by using Pythagoras law

p²+b²=h²

14²+11²=16²

317=256

It is not satisfied so

AB is not a tangent to the circle.

Answer:

4π cm

Step-by-step explanation:

GIVEN :-

TO FIND :-

FACTS TO KNOW BEFORE SOLVING :-

Circumference of a circle with radius 'r' is = [tex]2\pi r[/tex]

⇒ Circumference of half-circle with radius 'r' = [tex]\frac{2\pi r}{2} = \pi r[/tex]

SOLUTION :-

Radius = [tex]\frac{Diameter}{2} = \frac{8}{2} = 4[/tex]

So , Circumference of half-circle = [tex]\pi \times 4 = 4\pi[/tex] cm

Answer:

Options A, B, C

Step-by-step explanation:

From the graph attached,

Vertex of the given quadratic function → (0, 1)

Therefore, axis of symmetry → x = 0

Option A

Axis of symmetry ix the line represented by x = 0.

True

Option B

The y-axis is the axis of symmetry.

Line represented by x = 0 is the y-axis.

True

Option C

If the point (a, b) is a point on the parabola, then the point (-a, b) is also a point on the parabola, because it is a reflection over the axis of symmetry.

Rule for the reflection over y-axis is given by,

(x, y) → (-x, y)

Therefore, coordinates of the point (a, b) after reflection over the y-axis will be,

(a, b) → (-a, b)

True

Option D

The x-axis is the axis of symmetry.

False

Answer:

22 Hours

Step-by-step explanation:

Divide 8 by 176, 176/8 = 22

Answer:

You need to calculate (# of Boys) / (# of Girls + # of Boys). The largest ratio will be the biggest number

Step-by-step explanation:

Example:

• 55 Boys and 35 Girls

• Boys Ratio = (55) / (55 + 35)

• Boys Ratio = 55 / 90

• Boys Ratio = 61%

Answer:

70

Step-by-step explanation:

7 x 7 = 49

7 x 10 = 70

check

49/70

49 ÷ 7 = 7

70 ÷ 7 = 10

7/10

49/70 = 7/10

Answer:

No

Step-by-step explanation:

Linear values will increase by a common difference. For example, a linear function might increase by 6 every time or -4. However, this table does not; each time it increases by a different factor. Since there is no common difference and it does not follow an arithmetic function it is not linear.

Answer:

Step-by-step explanation:

Not linear.

If the inputs were 1, 2, 3, 4 and we wanted a linear function, one such function would be 1, 2, 3, 4 or 10, 20, 30, 40, and so on.

The given table shows that y increases faster and faster as x increases.

From x = 1 to x = 2, y increases from 1 to 2 (an increase of 1).

From x = 2 to x = 3, y increases from 2 to 6 (an increase of 4).

From x = 3 to x = 4, y increases from 6 to 24 (an increase of 18)

No, the table does not represent a linear function.

Answer:

P = 131 degrees

Step-by-step explanation:

We know that the sum of the interior angles of a triangle is 180 degrees

The exterior angles shown form a straight line with the corresponding interior angle

So the two interior angles can be calculated

The sum of two angles on a straight line is 180 degrees

By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180

Thus;

P + (180-162) + (180-149) = 180

P + 18 + 31 = 180

P = 180-31-18

P = 131

Answer:

The midpoint of CD is (3, 2)

Step-by-step explanation:

The movement of x is +2 from C to D and the movement of y is 16 from C to D

2 (C's x coordinate) +2/2 (to find the movement up to the x coordinate of the midpoint) and -6 (C's y coordinate) + 16/8 (to find the movement up to the y coordinate of the midpoint)

This is 2+1 as the x coordinate and -6+8 as the y coordinate that is (3, 2)
